I thought I'd explore GCP Dataflow. Clicking the "Try Dataflow Free" button dumps me into a billing admin page. Perhaps a sign of what is to come, but how do I actually try Dataflow? Or is it a product that just bills you? Super confused.

Reloading the Dataflow page changed the "Try Dataflow Free" button into a "Go to console" button. My expectation, as a user, is that if I say I want to try a product, it should take me to that product, not the billing page of that product. But maybe it's just me.
